I found the Lord Stone, the other day, and it's pretty cool : it gives 50 damage reduction and 25% magic resist ! Coupled with my breton blood (25% magic resist), a 20% magic resist on my shield and a 20% magic resist on my new amulet, i take only 10% magic damage (it's a bit overkill, but previously i always had trouble with spellcasters and dragon breaths, as in "they dropped me from full to 20% hp in seconds"). Oh and on the note of dragon breaths, have you noticed how effective the ward spells are against those ? It's just a bit tedious to switch, but maybe it deserves it's hotkey.
Also i noticed that giants give me way more skill xp than, say, bandits. At some point i was blocking a giant's attack and i saw my blocking skill going up. I blocked a couple more attacks and it went up again. And again. And then my heavy armor went up. So, I guess they make good sparring partners if you can take the heat. Maybe i'll pick up some dull weapon later, and bash at them to increase my one-handed skill (which has really fallen behind my other skills). I might even train skills that i don't use, to increase the difficulty again (now that i have proper Ebony equipment made with 100 smithing and 100 enchant, it's getting a bit too easy compared to my old Orcish set).
